Hi Luciana,
The cylc kill
command kills selected task jobs in a running suite, it doesn’t kill the scheduler program itself.
To get a suite to shut down cleanly, use cylc shutdown <suite>
or cylc stop <suite>
.
That should work fine. In rare occasions where a suite becomes unresponsive, as a last resort you can kill the Linux process as shown by @Rosalyn_Hatcher. (Note you can still do a restart, from wherever the workflow got to, even after a hard kill).
(See cylc kill --help
etc.)
Regards,
Hilary
